Phosphorus-based organocatalysis encompasses several subfields that have undergone
rapid growth in recent years. This Outlook gives an overview of its various aspects. In …

Hepta-2, 3, 5-trienedioates 1 have been employed as substrates to explore Lewis base-
catalyzed annulation reactions. This leads to the discovery of a phosphine-catalyzed [3+ 2] …

Abstract Lewis base dependent (3+ 3) annulations of β′/δ‐acetoxy allenoates with
iminoindolines offer α‐carbolines with varying substituents depending on the base used as …

The same δ-acetoxy allenoates and thioamides, under DABCO, pyridine, or tetra-n-butyl
ammonium bromide (TBAB) catalysis, undergo distinctly different annulations giving …

Lewis base dependent (3+ 3) annulation of δ-acetoxy allenoates with benzofuranone,
pyrazolone, and Boc-protected oxindole is reported. In the presence of catalytic DBU …

A highly selective phosphine-catalyzed β-addition of α-fluoro β-dicarbonyl compounds to
allenoates has been developed. Both α-fluoro β-diketones and α-fluoro β-keto esters prove …

Annulation reactions involving acetoxy allenoates and enolizable carbonyl substrates under
DBU (DBU= 1, 8-diazabicyclo [5.4. 0] undec-7-ene) catalysis is described in this paper. Thus …

Abstract Lewis base dependent (3+ 3) and (4+ 2) annulations of β′‐acetoxy allenoates with
N‐sulfonyl ketimines offer m‐teraryl and fused dihydropyridines with varying substituents …

In this paper, the base-mediated cascade reactions of 4-chloro-3-vinyl coumarins with β-
ketodinitriles were demonstrated, allowing the efficient synthesis of coumarin-based …

A protocol for the synthesis of trisubstituted furans via phosphoric acid‐catalyzed
regioselective cascade cyclization/amination of para‐quinone methides (p‐QMs) with β …
